A DICTIONAKY OP MINERAL NAMES.

In this work the author has endeavored to give the history
and etymology of every mineral name, including the following
points :

1st, the name correctly spelled;

2d, its author;

3d, a reference to its first publication;

4th, its original spelling;

5th, its derivation;

6th, the reason for choosing this particular name;

7th, a short description.

These particulars are fully given in most cases, but a number
remain incomplete, and a list of such is given herewith, in the
hope that information may be elicited, to be used in a subsequent
edition. The particular information wanted is noted against
each name, the word 'author' referring to the second point,

INTRODUCTION*

The study of mineral names is an interesting one, not only from the
mineralogist's point of view, as affording an insight into the growth aud
development of this branch of science, but also to the student of human
nature, for many traits of character are shown in the various considerations
which have determined the particular name to be adopted.

We sometimes find as the reason for a name the simple idea of distin-
guishing the thing itself; but this is not the most common reason. To do
honor to some person who may perhaps be pleased or flattered by the atten-
tion, or to immortalize some place, often otherwise obscure or unknown, is
a much more common reason. Names have been given to commemorate
battle-fields, to sneer at the work of earlier investigators, and as a tribute
to feminine loveliness. In short the whole round of human passions has
been gone over in the manufacture of these words, which are purely scien-
tific in their uses, and for the making of which scientific methods might
well have been employed. The subject has also no little Interest from the
pliilological side, and these names deserve study if only as part of our
language.

One of the most noticeable things about mineral names is the lack of
uniformity in their terminations. While the large majority of them end
in -ite, there are many in -ine, while -ane, -ase, -ose, and several others
have been often used. It is to be regretted that the termination -ite has
not been universally adopted, for it has been so far adopted as to be the
generally accepted one for such names. It has the sanction of antiquity,
for it was used by the old Greek writers in the forms ites or -itis, as in
ai/iaTiTTji, 'hematite,' and dXapaaTin'i, 'alabaster.' Such forms were
also used by the Romans, and we have in Pliny siderites, 'lodestone,'
steatitis, 'soapstone,' molochites, 'malachite,' and many others. These
forms are undoubtedly the source of the termination -ite now in use, as
they are the earliest known terminations. Such names were given by the
ancients as noting some property or use of the mineral, or sometimes desig

of Mineralogical Names,' read before the New Yorlc Academy of Sciences on January

nating its source, or the locality from which it was derived; as uayvfjiis,
a mineral from Magnesia. Or, to speak of those already mentioned,
aiudziTTii is a mineral resembling blood, so called from the color of its
powder; oiXafiaaTixii, a mineral from which a vessel called an alabastron
was cut; siderites, from aiSripoi, 'iron,' because it contains it; steatitis,
from a-rearoi, 'of fat,' because it feels greasy; and molochites, from
juaXax''?, ' mallows,' alluding to its green color. In the 5th edition of his
great work on Mineralogy, Prof. J. D. Dana makes an attempt at uniform-
ity of nomenclature by changing the terminations of many names into ite,
particularly those ending in -ine, only leaving those unchanged which had
come into too general use in the language to be so treated. So we have
galenite, alabandite, pyrrhotite, and periclasite, instead of galena, alaban-
dine, pyrrhotine, and periclase. These changes have been generally
adopted, and are all in the right direction.

In 1876 Prof. C. U. Shepard published a ' Catalogue of Minerals found
within about 75 miles of Amherst College, Mass.,' in which he proposed
that the names of all acknowledged mineral species, except those of the
elements and a very few more, shall uniformly end in -ite, and that the
termination -ine shall as uniformly be used for all variety names, and those
whose specific character is not fully settled. Accordingly, he gives us
gypsite, serpentite, wadite, orthoclasite, spodumenite, epidotite, and many
similar changes, while marmolite, picrolite, nacrite, and others are made
to end in ine, marmoline, picroline, nacrine. It is hardly necessary to say
that these suggestions have not been generally or fully accepted.

The use of the termination -lite, in German -lith, from the Greek ^z'floS,
'a stone,' ought here to be mentioned, as it was a genuine attempt to intro
duce a distinguishing mark for mineral names, which, if successful, would
have been of great benefit to mineral nomenclature, as bringing in the
desirable element of uniformity. This also comes from antiquity, being
found in the Greek. But it never came into general use, and in later years
is seldom used except for euphony. There is an erroneous impression
that the termination -ite is derived from this, which, as we have seen, is
not the case, as it is a much older form.

As all scientific works were written in Latin up to a very recent date,
and as there was no chemistry to show differences in composition, there
was no real progress in mineralogy. External characters alone were used
as means of distinguishing minerals from each other, and those that looked
alike must necessarily be classed together. Pliny's names were suflBcient
for all the uses of the science down to the sixteenth century. There was
hardly a name added, even by Agricola, whose large works were published
1529 to 1546. The name fluor is perhaps his only new one, and that he

probably did not originate, but look from the vocabulary of the furnace-
men, who used fluor-spar in smelting their ores. Certain minerals in general
use had their common names in various languages, but there were few of
them.

Several attempts have been made to give systematic names to minerals
on some such principle as is used in other branches of natural science, but
not one of them has been generally adopted, and all have by degrees been
dropped. One of the earliest of these was by Sir John Hill, in his ' History
of Fossils,' London, 1748. He divides minerals into numbered series,
classes, and orders, and under these into named genera and species. His
genus names are many of them new, but are sometimes older names modi-
fied to suit his system. For instance, Marmora, for the marbles. A good
example of his new names, and also of the way in which species were
multiplied when only external characteristics were considered, is in the
order of Inflammables. The 3d class is called PhlogoniiE, and under this
we have as the 1st genus, Pyricubia, and under this two species: 1st,
Pyricubium maximum foliaceum, and 2d, Pyricubium solldum minus.
The first of these species is simply those cubical crystals of iron pyrites
which are striated by an oscillation toward a hemitetrahexahedron, and
the second is the unstriated crystals of the same. Octahedral pyrite is
made another genus, and dodecahedral is still another. Several more
genera are made trom what is now the one species. This system never
■came into general use, and Hill himself gives it up and adopts one much
more simple in his later work entitled 'Fossils Arranged according to
their Obvious Characters,' London, 1771.

In 1820 Prof. Mohs brought out a small book entitled ' The Characters
of the Classes, Orders, Genera, and Species; or the Characteristic of the
Natural History System of Mineralogy. Intended to enable students to
discriminate minerals on principles similar to those of Botany and Geology.'
This system is more fully presented in his larger work of 1822-4, trans-
lated by Haidinger in 1825. He uses genus and species names for each
mineral, and sometimes adds a third for more exact distinction. Under
the genus garnet he gives Pyramidal Garnet, or idocrase; Dodecahedral
Garnet, or true garnet; and Prismatoidal Garnet, or staurolite. Dioptase
becomes Rhombohedral Emerald-Malachite. This system was quite popu-
lar for a time, and had several imitators. Prof. C. U. Shepard adopts
Mohs's system, and in the first edition of his mineralogy, 1832-5, he not
only uses his names, but extends the system still further. He, however,
gives first the common or trivial names, as they are called, and always uses
them in speaking of species. Microlite is the one new species of his own
noted in this book, which under the sj'stem he calls Octahedral Tungstic-

X INTRODUCTION

Baryte, and similar names are carried all the way through. None of these
names are mentioned in his third edition, 1853-7.

In 1836 Prof, J. D. Dana read a paper before the New York Lyceum
of Natural History, entitled ' A New Mineral Nomenclature,' in which he
presents a complete arrangement according to the Natural History method,
and gives some very good reasons for its adoption. This system is carried
out in full in the first edition, 1837, of his Mineralogy. He uses in general
two names for each mineral, as Andalusius prismaticus for andalusite, but
he gives the common name first in all cases. In his second edition, 1844,
he retains these Latin names as the scientific ones, and as necessary to 'a
systematic idea of the science,' but adds, p. 135, 'the shorter trivial names
should however be retained, as more convenient for common use.' In the
third edition, 1850, however, Prof. Dana discards the whole system, not
even retaining the names as synonyms. A system of arrangement is
adopted that was understood to be temporary, while at the end of the work
a chemical classification is suggested. In the later editions this last has
been perfected, and we now have an arrangement easy of reference and
answering all purposes of classification, but from which all traces of the
double Latinized forms of the Natural History methods have disappeared.
This or some similar system is now generally followed by writers on miner-
alogy, much to the satisfaction of those who use their works. In 1847
Glocker published his work entitled ' Generum et Specierum Mineralium
Synopsis.' This is perhaps the most successful attempt at a systematic
nomenclature that has been made. He uses in general a Latinized form of
the common name for the name of each species, with some descriptive
word added. For varieties he adds a third word, as is common in other
branches of natural history. For instance, under Granatus, garnet, he
gives three species: 1st, Granatus nobilis, precious garnet; 3d, Granatus
hyacinthinus, cinnamon garnet; and 3d, Granatus vulgaris, common
garnet, and under the latter he uses for varieties the terminations fuscus,
niger, viridis, flavus, and albidus. The work is in Latin, thus going back
to the style of the scientific books of the last century. Recently Prof. T.
Sterry Hunt has devised a new Natural System, suggested indeed as early
as 1853, but as he gives few new species names a discussion of it would be
out of place here. His work is, however, exceedingly interesting, and will
well repay examination by those who care to go further into that side of
the general subject.

In 1728 Dr. John Woodward published a work entitled ' Fossils of all
Kinds Digested into a Method, Suitable to their Mutual Relations ami
Affinity,' but it is a description from external characters only, and can
hardly be called a scientific treatise. The first one that really deserves-

INTBODUOTION XI

such a name is by the Swedish mineralogist Wallerius, in 1747, which is
arranged on a scientific plan, and gives us the earliest systematic descrip-
tion of minerals. Cronstedt, another Swedish chemist, ten years later gave
us a work of much greater value, as he brought in chemical relations, as
far as was possible in the crude state of that science. But few new names
were added, for the study was still largely from the external side, and new
species could not be recognized. With the discovery of oxygen in 1776,
and the real beginning of the science of chemistry, a more correct basis for
the differentiation of mineral species was found. This was aided by the
application of scientific crystallography, the first edition of de L'Isle's work
appearing in 1772, and the second, in four volumes, in 1783. From this
date new names were given to minerals as the result of more extended
research in this branch of study, and one of the first of these was prehnite,
given by Werner to a mineral brought from the Cape of Good Hope by
Colonel Prehn, and hence named after him. Werner first announced the
name in his lectures in 1783, as he himself states later, but it was not pub-
lished for several years. In 1789 there is an article in the Journal de
Physique, by Sage, objecting to the use of names of persons for minerals,
the text for which is this name of Werner's. But the name has kept its
place, and is now the accepted one for the species. Other names, given
about the same time after persons, are witherite, after Dr. Withering, who
first described it, and torberite, later changed to torbernite, after Torbern
Bergmann, its first analyst. This latter mineral has gone through various
vicissitudes as to its name, and a list of them, as an illustration, may not be
out of place here; they are taken from the 5th edition of Dana's Mineral-
ogy, p. 585: Mica viridis, 1773; Chalkolith, 1788; Torberite, 1793; Uran-
glimmer, 1800; Torbernit, 1803; Uranite, 1814; Uranphyllit, 1830; Cupro-
uranit, 1865.

The author's study of the history of mineral names was begun in the
interest of Murray's New English Dictionary, where these names are con-
sidered as words simply, and part of the language as found in books. The
information sought with reference to each is 1st, the author of the name;
2d, the date of its first publication; 3d, a reference to the original publica-
tion; 4th, its first form, if different from the one now used by English
writers; 5th, its derivation; 6th, the reason for the name; 7th, a short
description, sufficient to identify it, particularly if the name has been used
for more than one species or variety. A good example is Eriuite, a mime
given by W. Haidinger, 1838, Ann. Phil., 3d, iv, 154, from Erin, because
it was supposed to have been found in Ireland. It is a green, fibrous, arse-
Biat-e of copper. This description is necessary to distinguish it from Erinite
of T. Tliomson, 1836, Thorn. Min., i, 343, derived also from Erin, for the

XU INTRODUCTION

same reason, and properly so, for it came from Ireland. But this is a
reddish, clay-like mineral from the Giant's Causeway, and probably does
not merit a name at all.

Full information about many naiues is easily obtained, and is usually
to be found in the last edition of Dana's Mineralogy, up to 1892. But with
reference to a considerable number of names the information wanted is not
easy to obtain, and in some cases perhaps it cannot be found at all. When
it is not given in Dana's Mineralogy, the student may be sure that he must
search to find it. This is particularly true of obsolete names, information
about which must often be sought in the earlier volumes of scientific
journals. The first publication of T. Taylor's name killinite is in 1818, in
vol. xiii, p. 4, of the Transactions of the Royal Irish Academy, a fact not
given in any work on mineralogy. There are some names also about
which very erroneous ideas as to derivation prevail, and which need cor-
rection. The name chabazite was given in the form chabasie, by Bose
d' Antic, 1780, Jour. d'Hist., ii, 181, and is derived from ;i;ar/SaC205, the
name given to one of the stones mentioned in the Orphic poem ' Ilepi
XtQor.' 'The name as we now have it in the poem Is x'^^'^'Z^oi, and the
mineral should therefore have been called chalazite. Kidd called attention
to the blunder in 1809, Kidd Min., i, 249; but the original name has held
its place. It is but fair to say that the form x^'P^'Zioi was used in the
current editions of the poem at the time the name was applied. The deri-
vation of the word datholite has often been incorrectly given. It is really
a corruption of the original name datolith, given by Esmark in 1806, from
SarSo/iai, to divide, alluding to the granular structure of one of its
varieties, and AzfloS. Werner added the h for no apparent reason, and the
changed form was adopted by most authors until Prof. Dana, in 1868, un-
riddled the matter and gave it its correct form again. But wise writers
have tried to find another derivation for it, and one author of note says it
is from SafloS, which he says means turbid, because the mineral is not
clear and transparent. A wiser one says there is no such Greek word as
ddBoi, which is true, and that it is from the compound word 8a-6oXXos,
meaning very turbid, because it is never found in transparent crystals,
which is no more a proper derivation than the other. The word feldspar
has been changed into felspar for no better reason than that the latter form
was thought the right one. It was used by Wallerius in his Mineralogy
of 1747, p. 65, in the Swedish form felt-spat, meaning fleldspar. It did not
originate with him probably, but may have been a popular name in his time.
Da Costa used it in 1757, Nat. Hist. Fossils, 287, in the German form feld-
spath, and this form was current until 1794, when we find in Kirwan's
Mineralogy, vol. i, p. 317, the following note: ' This name seems to oe

INTRODUCTION XIU

derived from fels, a rock, it bbing commouly found in granites, and not
from feld, a field; and lieuce I write it thus, felspar.' This assumption of
Kirwau has been taken for fact by all English writers, and the corrupt
form is in very general use. Another interesting case is that of the name
pyroxene, which is popularly supposed to have been given, from nvp,
'fire,' and ievoi, 'a stranger,' in the idea that it is of rare occurrence
among volcanic rocks, while in fact Hafly expressly states, 1801, Hal'iy
Min., ii, 64, that it is very abundant among the volcanic matters of Vesu-
vius, Etna, etc., but is there as a stranger, the name expressing that it
is not m its native place, but existed in the non-volcanic rocks which
furnished the original material of the lava.

Authors often omit giving the reason for adopting a name. Where it
is on account of some characteristic of the mineral, its author often takes
it for granted that it is as evident to others as to himself. The name
coracite, J. L. Le Oonte, A. J. S. , 2d, iii, 117, is a case in point. Le Conte
does not give any derivation, but it is the name of a pitch-black variety of
uraninite, and is probably derived from icopa^, a raven. A similar case is
that of adinole, Beud. Min., 1832, ii, 126. No derivation is given, but it
may easily be conjectured from the description that it is from dSivoi, ' com-
pact.' But there are other cases where there is nothing suggestive in the
descripti9n, and even conjecture is at fault. Such conjectures if stated as
such are of value, but to give them as facts, as has often been done, is cer-
tainly a serious blunder, if not something worse. In one of the large dic-
tionaries we find the name acauticone derived as follows: from 'Greek
ocKri, point, ocvTi, against, and Kwvoi, cone.' This is a mere guess. The
name was given by B. J. d'Andrada, 1800, Jour, de Phys., ii, 240, in the
form akanthicone, and is derived from iXKavBii, a gold-finch, and Kovia,
powder, because the color of the powdered mineral is yellow. A similar
blunder is made with the name alvite, so called after one of its localities,
Alve, Norway. In the dictionary it is said to be derived from alvus,
the belly. Another instance of a mistaken derivation is that of coveite, an
obsolete synonym of agalmatolite, popularly supposed to be from Oorea,
probably because agalmatolite is from China, and Corea is close by. The
name was given by /. 0. Delametherie in 1795, and he derives it from
xoipeioi, ' of a swine,' because of its greasy appearance. He at first calls
it koireiite, but changed it to koreiite, and then to koreite, which has since
been changed to its present form, resembling one derived from the name
Corea. But the name should be choireiite, commencing with e/t.

Sometimes errors of the compositor have failed of correction, and these
spurious words have found their way into later books as real names. One
of these is glorikite, 1859, Duf. Min., iii, 326, which is an error for glinkite.

XIV INTRODUCTION

Gibsonlte, in the 1847 edition ot tbe same work, iii, 761, is probably aa
error for gibbsite, but this is not so clear. Galadsite, galadstite, and galad-
tite are all printer's errors for galaktite.

A curious case of this sort is seen in the various forms of the word
didymlte. It was announced by C. E. SchaufhauU in 1843 from Sidv/no';,
a twin, because it was thought to be a second silicate containing calcium
carbonate as part of its composition. The form was by some blunder given
as didrimite, but this was soon changed by the author himself to the cor-
rectly derived form, didymite, the original v being properly changed to y.
Of this word you will find in the books four different forms, only one of
which deserves any place in mineralogy.

Breithaupt gave the name kupholit, from ;i;ov0oS, light, and Az'flo?, to
a very light variety of serpentine. He leaves out the o of the original
word, probably because the word koupholite had been used before, being
an obsolete synonym of prehnite. This was first changed to kuphoite and
then to cyphoite, which gives little idea of its original derivation and
meaning.

Many more instances might be cited, but enough has been said to show
how much confusion has arisen through carelessness or unwarrantable
assumption, and how desirable it is that it should be disentangled as far as
possible.

In this work the endeavor is made to give complete information, as
outlined above, concerning all the names that have ever been introduced
into the nomenclature of Mineralogy. Nearly all published works on this
subject have been searched to prepare a complete list of such names, and all
available sources of information have been consulted. Many facts have
been received in private communications from correspondents at home and
abroad, a list of whose names is appended. But a number of blanks still
remain, after years of research, and the author greatly desires information
on any of the points lacking.

A number of personal names are not given in full. The use of the
surname only has been common with foreign writers, and in some early
cases it is perhaps now impossible to complete them. One of these is that
of Uttinger, author of the name natrocalcite. A recent and very re-
markable case is that of the late Adam, of Paris, author of the ' Tab-
leau Mineral ogique,' Paris, 1869, and an honorary member of the Societe
Mineialogique de France at the time of his death in 1881. The most per-
sistent effort has failed to disclose his full name. In answer to a letter of
inquiry on the subject the venerable Prof. Des Cloizeaux, his life-long
friend, says: ' M. Adam est mort tr6s vieux, laissant une remarquable
collection de mineraux 3, 1'ficole des Mines de Paris. II a toujours occup§

Words have not been inserted under every change of spelling, but only
ihose necessary to a complete understanding of each case. Some of the
variations between c and k, i and y, and c, s and z have been omitted.
Meither have forms in other languages been included where they are
simple translations of the English names. Chemical names are also left
out, except such as have the sanction of use as actual mineral names. By
this means the number has been kept down to the four thousand six hundred
and twenty-seven names here given, without omitting, unless by oversight,
any that should be found in a work of this character.

Following the Dictionary proper is an Index to the Authors of Mineral
Names, which it is believed will be found of interest, as showing just what
names each one has given. It has been found exceedingly useful in the
preparation of this work.

In the abbreviated references ordinal numbers refer to series, Roman
numerals to volumes, and Arabic numerals to pages unless otherwise
stated. Numbers or letters in parenthesis mean parts, and the numbers
immediately following the authors' names, which are always in italics, are
the dates. If the original reference has not been accessible, it is enclosed
in brackets, and a second reference which has been verified follows im-
mediately. Where the original form of the name differs from its present
English form, it is given in parenthesis immediately after the reference.
Thus: 'MOROXITE. P. C. AUldgaard, [1798, Moll Jabrb., ii, 433],
1803, Reuss Min., ii, (2), 349 (Moroxit),' means that the name Moroxite was
given by Abildgaard in 1798, and first appeared in von Moll's Jahrbucher
der Berg- und Huttenkunde, volume ii, page 483, according to Reuss'
Lehrbuch der Mineralogie, 1802, volume ii, part 2, page 349, where it is
spelled Moroxit.
